IQ4 updates?

At the time of the IQ4 release there was chatter related to a new UI and several new devices (eg new PowerG secondary panel). Is there any updates on these items? Wondering if they’ve been shelved.

There haven’t been any new releases as far as I am aware. It may have been delayed due to ongoing disruptions in supply chains if there were plans for one. I do not see reference to new models having been supported in firmware.
